PROBLEM TO BE SOLVED: To enhance the efficiency and continuity of extraction by continuously supplying a gas material into a fine pipe with a predetermined inner diameter or less along with pure water to hydrolyze the same, and continuously measuring the concn. of an ion component in the obtained extract. SOLUTION: A gas material is introduced into a collision part 1 along with pure water from an inlet, and the gas material and pure water are allowed to collide with each other to be mixed to form a flow in a fine gas-liquid mixed state. Next, the mixed flow is supplied to an extraction part from a fine pipe with an inner diameter of 3 mm or less. The extraction part has the fine pipe with an inner diameter of 3 mm or less as a fundamental structure, the gas-liquid mixed flow discharged from the gas-liquid mixing part is introduced and supplied into the fine pipe in a fine gas- liquid mixed state, and a hydrolyzable component in the gas material is hydrolyzed in the sufficient and continuous contact state with pure water during the passage through the fine pipe. Next, the mixed flow of the extract and gas component obtained in the extraction part is introduced into a gas-liquid separation part, the extract is separated from the gas component to be continuously introduced into a measuring part, and the concn. of the ion component in the extract is continuously measured herein. |
